Step by step in SiteGround

Verify your domain

Your email provider needs proof that you control this domain before it accepts email for it.

Type
TXT
Name
Leave this field empty
Value
Copy it from Proton Mail settings (Domain names) (see below)

Where to find your value

In Proton Mail open Settings → Domain names, add your domain and copy the verification value.

In SiteGround

  1. Under Create New Record, open the TXT tab.
  2. Enter only the prefix in Name (SiteGround adds your domain) and the Value.
  3. Click Create.

Point your MX records

MX records tell every other mail server where to deliver email for your domain. They must point to your provider and nowhere else.

Type
MX
Name
Leave this field empty
Priority
10
Destination
mail.protonmail.ch
  • Delete any other MX records, or make sure Proton's have the lowest priority number.
Type
MX
Name
Leave this field empty
Priority
20
Destination
mailsec.protonmail.ch

In SiteGround

  1. Under Create New Record, open the MX tab and choose Add your own MX records.
  2. Leave Name empty, enter the Priority and the Destination.
  3. Click Create.
  4. Under Manage DNS Records, delete SiteGround's default MX records.
  5. Repeat for each MX record above.

Add the SPF record

SPF is a TXT record that lists the services allowed to send email from your domain, so receivers can spot forgeries.

Type
TXT
Name
Leave this field empty
Value
v=spf1 include:_spf.protonmail.ch ~all
  • Keep one SPF record. To keep an existing one, add include:_spf.protonmail.ch right after v=spf1.

In SiteGround

  1. Under Create New Record, open the TXT tab.
  2. Enter only the prefix in Name (SiteGround adds your domain) and the Value.
  3. Click Create.

Set up DKIM

DKIM publishes a public key so receivers can confirm your messages really came from you and were not changed on the way.

Type
CNAME
Name
protonmail._domainkey
Resolves to
Copy it from Proton Mail settings (Domain names) (see below)

Where to find your value

Copy the exact target from the DKIM tab of your domain in Proton Mail settings.

  • Add all three DKIM records; Proton rotates keys between them.
  • Some hosts reject a trailing period on CNAME values. If yours does, remove the final dot.
Type
CNAME
Name
protonmail2._domainkey
Resolves to
Copy it from Proton Mail settings (Domain names) (see below)

Where to find your value

Copy the exact target from the DKIM tab of your domain in Proton Mail settings.

Type
CNAME
Name
protonmail3._domainkey

Copy it from Proton Mail settings (Domain names) (see below)

Where to find your value

Copy the exact target from the DKIM tab of your domain in Proton Mail settings.

In SiteGround

  1. Under Create New Record, open the CNAME tab.
  2. Enter only the prefix in Name and the target in Resolves to.
  3. Click Create.
  4. Repeat for each CNAME record above.

Add the DMARC record (recommended)

DMARC tells receivers what to do with mail that fails SPF and DKIM, and where to send reports about it.

Type
TXT
Name
_dmarc
Value
v=DMARC1; p=quarantine
  • Proton recommends a p=quarantine policy for most domains.

In SiteGround

  1. Under Create New Record, open the TXT tab.
  2. Enter only the prefix in Name (SiteGround adds your domain) and the Value.
  3. Click Create.

Check your setup

Once the records are saved, run a live check. We look up your domain in public DNS and tell you what is right, missing or wrong, with the fix in SiteGround’s words.

We only read public DNS records. Nothing is stored.

Common mistakes with Proton Mail on SiteGround

Adding only one DKIM record

Proton uses three DKIM CNAMEs (protonmail, protonmail2, protonmail3). Add all three, matching the values in your setup wizard exactly.

SiteGround: Delete SiteGround's default MX records

New sites start with three MX records for SiteGround's own mail: mx10, mx20 and mx30.antispam.mailspamprotection.com. Remove them when you use another provider.

SiteGround: SPF lives under Email > Authentication

SiteGround manages SPF in Site Tools > Email > Authentication. Edit the Include List there instead of adding a second SPF record in the DNS Zone Editor.
